Specifically, one vring can use multiple different DMA +channels and one DMA channel can be shared by multiple vrings at the same time. Vhost enqueue operation with CBDMA channels is supported +in both split and packed ring. + +This document provides the test plan for testing some basic functions when Vhost-user using asynchronous data path with +DSA driver (kernel IDXD driver and DPDK vfio-pci driver) and using 4K-pages memory environment. +1. test Vhost asynchronous data path with DSA driver in the PVP topology environment with testpmd. +2. check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring +vhost-user/virtio-net mergeable path. +3.Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring +and packed ring vhost-user/virtio-net mergeable and non-mergeable path. +4. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring. +5. Vhost-user using 1G hugepges and virtio-user using 4k-pages. + +DPDK 19.02 add support for using virtio-user without hugepages. The --no-huge mode was augmented to use memfd-backed +memory (on systems that support memfd), to allow using virtio-user-based NICs without hugepages. + +Note: +1. When DMA devices are bound to vfio driver, VA mode is the default and recommended. For PA mode, page by page mapping may +exceed IOMMU's max capability, better to use 1G guest hugepage. +2. DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd, and the suite has not yet been automated. + +Prerequisites +============= + +General set up +-------------- +1.
